College Answer

1. Nystagmus
2. Titubation (head bobbing)
3. Truncal ataxia
4. Staccato speech
5. Dysarthria
6. Hypotonia
7. Kinetic tremor

Discussion

This is cheating, because kinetic tremor and hypotonia are difficult to test without involving the limbs.

Walker, in the below-linked book chapter, identifies the following signs:

  • Titubation
  • Resting tremor of the trunk
  • Trunkal ataxia
  • Nystagmus
  • Ocular dysmetria (the eyes overshooting the target of their gaze)
  • Impaired smooth tracking of gaze
  • Stacatto speech
  • Dysarthria (ataxia of speech)
